CLVTH16543IDGGREP

Overview

The CLVTH16543IDGGREP is a dual 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features LV TTL input and output levels. The device provides three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 2.8 ns and is housed in a 56-pin TSSOP package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides registered data storage for stable signal transmission across bus interfaces
• Enables bidirectional level shifting between 3.3 V logic systems and compatible buses
• Features three-state outputs to isolate the driver from the load when disabled

Applications

• High-speed data acquisition systems requiring registered buffering
• Industrial control networks utilizing 3.3 V microcontrollers
• Memory interface circuits demanding precise timing registration

Procurement Notes

Verify the specific suffix IDGGREP against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure the order matches the exact RoHS compliance status and lead time requirements specified in the latest datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when designing systems that require registered bus isolation with 3.3 V operation. It is suitable for applications needing high drive strength and low propagation delay. Compare it against non-registered variants if latching functionality is not required. Ensure the system voltage remains within the 2.7 V to 3.6 V range for optimal performance.

Part Context

This device belongs to the enhanced C-VTH series, which offers improved performance over standard LVT parts. It is functionally similar to the SN74LVT16543 but includes specific enhancements for reliability and speed. The TSSOP-56 package allows for compact surface-mount designs in dense PCB layouts.

Replacement Considerations

The SN74LVT16543DLG4 is a registered alternative in the same family. Verify pin compatibility and electrical specifications before substitution.
